Description
Technical field
The present invention relates to a kind of soil sample sampler and its soil basketing method.
Background technology
Wetland soil is an important component part of wetlands ecosystems, and wetland soil is chronically at ponding or in growth
Under Ji Jishui, the environmental condition of periodicity waterflooding, it is flat or low-lying that principal character shows as landform, impeded drainage, various dynamic plants
Thing Residue decay is slow or is not easily decomposed, and the generation of organic substance exceedes its decomposition, causes accumulation organic in a large number, and
And contain substantial amounts of root system of plant in soil, soil texture is loose, have larger porosity, the field investigation of wetland soil,
The test of the soil physical properties such as the soil weight, porosity and some culture experiments are required for gathering original state wetland soil sample
Product.Can soil physical property measures and whether analysis result is true and reliable, relevant issues are scientifically described, it is preferred that emphasis is soil
The collecting work of the collection of sample and process, wherein pedotheque is premise and the basis entirely analyzing work, wetland soil
Acquisition quality directly affects the accuracy of correlative study work, science.Therefore carry out the wetland soil of science according to experiment purpose
The collection of earth original state sample is most important.
Adopt mining method and soil drilling method conventional wetland soil sampling method more, during operation, there is compacting, extruding, disturbance work
With frequently resulting in that taken depth of soil data precision is poor, greatly reducing reliability and the accuracy of data.With regard to minor diameter
(5cm) adopt low temperature boring method wetland soil column sampling method, application high-pressure liquid nitrogen tank storage liquid nitrogen scene makes wetland soil more
Earth freeze after with copper pipe sampling, exist carry in-convenience in use, the problems such as cost height, and be difficult to obtain major diameter
Wetland earth pillar sample, soil freezing process on soil property impact larger it is impossible to realize original state wetland soil sample well
Collection.The soil sample collector part of other major diameters carries scale, but scale is labeled on sampling cylinder wall, in surface pond wetland
Depth selection cannot be observed during sampling.
Wetland soil is because the content of organic matter is high, contain substantial amounts of root system of plant, and soil texture is loose, has larger
Porosity, there is potential compaction during soil sample, be difficult to from wetland obtain more than 10cm diameter earth pillar
Sample.
Content of the invention
The present invention is directed in conventional soil sample collector sampling process has compaction it is more difficult to observe depth selection, uncomfortable
Problem for wetland soil sampling.The present invention is for the extruding to soil when down-sampling, thus ensureing depth selection precision,
